      CPU and System Topology

      Server Description

      An x86_64 memory-optimized configuration featuring high memory density, a fast clock speed, and strong single-core performance for memory-bound workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure FX8ms_v2 is an x86_64 memory-optimized server powered by an Intel Xeon 8573C processor running at 4.2 GHz. It features 8 dedicated vCPUs across 4 physical cores, supported by a 260 MB L3 cache and 168.0 GB of RAM, providing a high memory-to-core ratio of 21.0 GB. The server lacks local storage and GPUs but supports premium storage. Benchmark data highlights top-tier single-core performance, with Geekbench single-core and text processing scores in the top 10% tier, alongside strong single-threaded compression speeds. Conversely, multi-core benchmarks and medium-model LLM text generation show average to weak performance, reflecting the physical core limitation. This configuration is qualitatively cost-efficient for memory-bound, single-thread-heavy applications. It is best suited for memory-intensive databases, text processing, and workloads requiring high memory capacity per vCPU.

      Workload Profiles

      0.93Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
